2020 Honda CR-V: check engine light

Filed Aug 25, 2026 · Engine, Fuel system · CT

The check-engine light comes on immediately before the vehicle loses the ability to accelerate. While driving, including at highway speeds, pressing the accelerator does not produce normal propulsion and the vehicle loses motive power. If I pull over, turn the vehicle completely off and restart it, the check-engine light clears and normal acceleration returns. The problem is intermittent and has occurred more than once. The dealership has previously been unable to identify the cause because the vehicle operates normally after restarting.

When driving on highway, the engine light came on and the car suddenly slowed down causing me concern about traffic around me still going at highway speed. Not understanding what the issue was and afraid the car would lose all power, I was able to shift lanes quickly to get to the breakdown lane. I was able to get the car to Honda Dealer driving at slow speed using back roads. The Honda Dealer confirmed an engine misfire caused the engine light and slowdown. The cause of the misfire was coolant leaking into engine cylinder and would require replacing the head gasket to fix the problem. The car had 75,000 miles and had been running fine until that point.

I got onto the free and accelerated to the speed limit. I glanced at my dash and saw the check engine light start flashing. I could feel the car start to lose power and handle differently than normal. I immediately pulled to the shoulder and had the car towed to the dealership. They diagnosed it as having a blown head gasket and that coolant had gotten into 1 of the cylinders. The adviser informed me that 2018-2022 1.5 turbo and hybrid engines have been having issues with blown head gaskets. I had also been seeing complaints of that on social media before this happened to mine. My vehicle has over 100k miles and it isn’t even 6 years old. I have had older Hondas, acuras and Toyotas with similar mileage or more and no issues like this. If so many drivers are having blown head gaskets Honda needs to be looked into for this and have a recall to repair their defect. The service adviser told me it was nothing I had done to my vehicle to cause this. I get oil changes when the maintenance light comes on and I have completed scheduled maintenance on my vehicle. I also use Costco gas 95% of the time and only use other brands when traveling.

My 2020 CR-v hybrid has suddenly lost power on the freeway a total of 4 times in the 6 years I've owned it. It is always at freeway speeds. The flashing engine light appears and the car loses power. After pulling over, turning off the car, and waiting a few minutes, the car can be turned on and driven with no more flashing engine light and no more problems for months. Each time I've taken it to the dealer and each time they haven't been able to replicate or find the problem. I've been told that error codes were not generated. I purchased my car new in July 2020, and the power-loss incidents were: - Fall 2020 - Summer 2022 - December 2024 - June 2026 A google search shows that many other crv hybrid owner have experienced the same problem, and also have had service technicians unable to find problem. This is a major safety concern.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system and engine power management. The vehicle suffers from sudden "Limp Mode" activation and total loss of acceleration. The vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? My safety was severely compromised when the vehicle suddenly lost power while traveling at highway speeds. This occurred twice in high-speed traffic, creating an immediate risk of a rear-end collision as the vehicle could no longer maintain the flow of traffic or accelerate away from danger. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? No. The issue was reported to a dealer in 2024, but because the malfunction indicator lamp (MIL) turned off after a restart, the dealer was unable to reproduce the failure or find stored error codes at that time. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, it was inspected by an authorized Honda dealer in 2024, but no repairs or actions were taken as they could not replicate the fault. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. There were no prior symptoms or early warnings. In both incidents (2024 and yesterday), the engine light illuminated simultaneously with a sudden, localized loss of speed and a total inability to power up or accelerate while on the highway.

I am experiencing intermittent loss of motive power. Without warning at highway speeds I get a flashing check engine light immediately before the loss of motive power occurs. Motive power can be restored by turning the ignition off and back on. However, this action also clears the check engine light and any fault codes that were set. I drive with a code reader in the car and have received a P0302 code. This has happened at least five times since May 2024. It is available for inspection. I have brought it into a Honda dealership for repairs, they have changed the fuel injectors and pistons and it is still occurring. I was told this time that they did not know what was wrong so they could not repair anything. The safety of myself, my husband, and my seven month old daughter was out at risk as it occurs when traveling over 55 miles/hour and we lose power. We have to try and navigate to the side of the road to turn on and off the car. This problem was reproduced by a dealer this last time it went into the shop and it is there currently. The vehicle has only been inspected by Keeler Honda in Latham, New York. There were no other warnings prior to this failure. It has occurred multiple times, May 2024, November 2024, Feb 2025, March 2026 I have a video of what happens but I cannot upload it. This is exactly what is happening in the federal safety agency Action Number: PE25016
